European Hornets

Identification: European hornets, commonly found in Muskoka, are large wasps measuring between 18 to 25 mm in length. They are characterized by their yellow and brown coloration, featuring a robust body with distinct yellow stripes across the abdomen. European hornets have a broad, flat face and long, slender legs, making them easily distinguishable from other wasp species. Unlike smaller wasps, they have a more substantial and intimidating appearance.

Habitat: In Muskoka, European hornets typically build their nests in sheltered areas, such as tree hollows, wall cavities, and attics. Their nests are made from a paper-like substance created by chewing wood fibers mixed with saliva, resulting in large, round structures that can contain hundreds of individuals. These nests are often located high off the ground and can be hidden within foliage, making them somewhat less visible but still a potential threat near homes and gardens.

Diet: European hornets are omnivorous, feeding primarily on a variety of insects, including flies and caterpillars, which they capture and bring back to the nest to feed their larvae. They are also attracted to sugary substances, such as fruit and nectar, making them common visitors at outdoor picnics and gatherings. Their diet not only helps sustain their colonies but also plays a role in pest control, as they help manage insect populations.

Behavior: European hornets exhibit a highly social structure within their colonies, which includes a queen, workers, and drones. They are known for their defensive behavior, particularly during late summer and early fall when they become more aggressive in protecting their nests. European hornets communicate using pheromones and visual signals, coordinating their foraging and defense activities effectively. Understanding their behavior is essential, as they can pose a significant threat when their nests are disturbed.

Prevention: To prevent European hornet infestations, proactive measures are essential. Regularly inspecting properties for potential nesting sites, especially in the spring, can help reduce the risk of infestation. Keeping food and garbage tightly sealed and minimizing outdoor attractants can deter these hornets from frequenting your yard. Bug Free Muskoka’s General Pest Control Service provides an effective solution by creating a protective barrier around your home, targeting potential nesting areas and entry points to reduce the likelihood of hornet invasions.

Control: Managing European hornets requires careful identification and safe removal of their nests. This is best done in the evening when hornets are less active. Insecticidal sprays specifically formulated for wasps can effectively eliminate nests from a distance. Regular inspections of potential nesting areas, combined with early intervention, are crucial in minimizing the risk of infestations. For safety and efficacy, it’s advisable to consult Bug Free Muskoka for larger nests or if aggressive behavior is observed.
